Romania took the crown in a time of 6min 06.400sec as they finished ahead of Canada and New Zealand.

"The next years look promising.”

Germany ended a run of near-misses in the men's eight race at major events as they claimed the title on the final day of action .

The German team, the London 2012 Olympic gold medallists, had finished second at Rio 2016 and the 2015 World Championships but returned to the summit of the podium with a clinical display today.

They completed the course in a world leading time of 5:26.850sec, crossing the line in front of the teams from the United States and Italy, who were second and third respectively.

"Honestly, I think the work in the two months before this event was so much tougher than the actual race," Germany's Hannes Ocik said.

"Staying focused for so long was a real challenge. 

"It was such a good feeling crossing the finish line today.”

Ondřej Synek of the Czech Republic, a three-time Olympic medallist, claimed his fifth world title as he stormed to victory in the men's single sculls in 6:40.640.

Filippo Mondelli and Luca Rambaldi of Italy came through to take bronze.

New Zealand also claimed victory in the women's double sculls thanks to Brooke Donoghue and Olivia Loe, who clocked 6:45.080 to claim gold ahead of Meghan O’Leary and Ellen Tomek of the United States and Australia's Olympia Aldersey and Madeleine Edmunds, silver and bronze medallists respectively.
